DETACHALBLE LINING FOR BRAKE-BANDS.

aaai-Leie.

Application filed September 2, 1919.

To zZZ whom may conce r-n Be it known that JosEPH lV. Enum. citizen of the `United States. residing at Cleve land, in the county of uyahoga and State lof iiio, has invented certain .new and useful improvements in a Detachable Lining for Brake-Randa of which the following is a specification.

This invention consists in a detachable lining for a 'rietion brake or clutch hand adapted to be employed especially in motor vehicles, all substantially as shown and described and more particularly pointed out in 'the claims.

in the accompanying drawings- Figure 1 is a side elevation of what may lic regarded as a-braie or clutch Wheel. or its equivalent. fixed rigidly on a shaft and having my new and improved liralie mechanism about the same. Q is an edge vieiv of tivo such wheels located side hy side on the saine, shaft and showing the lining member sectioned oil at top and. bottoni of the Wheel at the right. Fig. 3 is a perspective detail of the lining member alone. and Fig. i is a side vievv a portion of one of the liralze ivlieels or slieei es and a section of the brake mechanism enmerentially ano an end section oi@ 'alle lining Vn'lei'ncer betireen said parts.

The complete structure as thus shoivn eoniprises the shaft a. the Wheel or sheave 'ze thereon, the 'brake hand and the :so-called lining or friction ineinoer ci, as a separate article oi. manufacture and sale.

For the purpose ot the prese-nt description it may be assumed that `the shaft a is a power driven shaft in an automobile or like vehicle in which one or more brake or like Wheels are einpoyed, and some such machinos are known to employ7 two or. three such Wheels or clutch members on the same shaft. rliese usually are equipped with ifrietioii brake or clutch mechanism in which the band Z) is employed as the active medium for making the engagement.

The said hand is adapted'to encompass the Wheel or drum except between its ends which are spaced'apart a sutcientdistance to pro-A vide for opening and closing in friction relations about the wheel. and said ends have lugs standing outwardly therefrom and provided with open. slots adapted to receive the reduced and partially screwlireaded end of the operating rod #i therein. The said Specification of Letters Patent.

Serial No. 321.021.

reduced end of the rod is secured liv a nut on its extremity hearing against the outer lug. ivhileI a shoulder (l on said rod hears against the inner oie said lugs or projerlions. A comparativa` y strong spiral spring T encirclcs said rod lietxvcen said lugs and .serres as a spreader ot' the ends of he hand againr.;` the lugs. thus spreading the hand and holding it normally out of liralic relations. it ivill he noticed. also. that the. said hand 7 has slight terminal projections S outside .said lugs'and the brake lining c as a distinct. and separate embodiment comprises a shcet metal body 10 of hand shape and a suitable lfrictional facing 1Q on its insides` preferably o' ytextile material and treated or otherivise made to ai'lord good Wearing and trici-ional qualities. hut any suitable iictional facing may he employed. The part oi'- liody lll is pieiceraliiy of spring steel.

The said lining attachment is designed especially to lie convenient 'for removal and replacement when ivorn or otherwise impaired for effective service. and to those ends is provided with a substantially lioolosliaped lip ll on each cud hy hcnding the extremity hack upon itscli" outwardly and lock upon thc shoulders ol the lirahe. hand. as clearly and said body 10 is also proi d fiaiiges, in staggered relati` at intevals along its enges and adapted to hear against the, edges ot `the hand l. thus cinfining the said member yor lining on said handand yet leaving it in shape to he easily removed and replaced liy :in unskilled person.

Now, assuming that the brake lining is to lie remoif'ed for renewal. or repair or other cause. there are two Ways in which this he done. one. of which is by pushing the linn ing around endwise Within the liralre hand. but the preferable Way is to remore the lining laterally. This is accomplished "mi firstloosening the mit. on the ci so as io permit the 3 brake band to spring a," seen iii L or to iiie maximum the band casing.r out Without. rod Ifrom its seat. 'fhe also relieved off tension and Tesis loose lie rod. The next step is to release one end of the lining from the liralie hand and o shove said end bacia under the imi s .ments an vbrake band, with the clutch in neutral to permit the drum to be turned to facilitate the operationy This brings Ithe lining to relations Within the arts to Work the. same laterally from the rum for removal. In

this opera-tion the end of the lining is placed y obli uely to the axis of the brake band until one ooked end is projected beyond or to one'side of tlle outer edge of' the brake band so as to clear the operating shaft and spring.

e ining can then be.

The exposed end of th grasped by the hand and the lining drawn out endwise with a direct pull.

The mode of operating the brake band 2 and the working relation of the' band to a housing or casing, or to other coacting parts .of a machine, is not shown inasmuch as the invention resides more (guiding flanges, Whereb 're lacerepairs may be quick y e ected and side without removing o'r a screw. driver or the like is' the 'ends of said particularly in the -iiexible lining member with its holding lips ssembling the brake or clutch members from the .shaft or housing. i

What I claim is:

1. As a new article of manufacture, a lining for a brake band and the like having hook (shapedv ends adapted to engage over band and projections along its edges adapted to bear against the edges of said band, and said lining faced with frictional material on its inner side.

2. As a new' article of manufacture, a lining lfor brake bands and the like co`mrising a sprin metal body of band shape avin outwar y-turn'ed hooks at its ends and anges staggered invrespect to each other at yits o posits edges and vadapted to bear against t e edges of the brake band.

3. vA. removable and replaceable' clutch lining, comprising a flexible metal band having hooks at its opposite ends and guiding and holding lips 1n staggered relation on its opposite side edges.
